and (-)-4, conferred higher affinity at alpha(1)-adrenoreceptors, whereas a 1S configuration, as in (-)-3 and (+)-4, produced higher affinity for 5-HT(1A) receptors. For the enantiomers (+)-4 and (-)-4 also a remarkable selectivity was achieved. Functionally, the stereoisomers displayed a similar alpha(1)-selectivity profile, that is alpha(1D) > alpha(1B) > alpha(1A), which is different from that exhibited
WB 4101(1)-相关的苯并二恶烷的合成是通过用环戊醇部分取代6将胺和1的苯氧基单元分开的乙烯链,该环戊醇部分为6、7-二氢-5-[[(顺-2-羟基-反式-3-苯氧基环戊基)氨基]甲基] -2-甲基苯并[b]噻吩-4(5H)-据报道在α(1)-肾上腺素受体上显示出有趣的选择性。这种合成策略导致16种可能的立体异构体中的4种在(-)-3,(+)-3,(-)-4和(+)-4的情况下被分离出来,并且其绝对构型是使用从(+)-(2R)-2、3-二氢-1,4-苯并二恶英-2-羧酸((+)-9)和(1S)出发合成(-)-3的手性构件2S,5S)-2-氨基-5-苯氧基环戊烷-1-醇((+)-10)。该项目的目的是进一步研究是否有可能区分这些化合物对α(1)-肾上腺素受体亚型的亲和力和对5-HT(1A)受体的亲和力,因为1在两种受体系统。通过在分离的大鼠输精管(alpha(1A)),脾脏(alpha(
